Answer: Thanks for your question Randy! I
believe children should not throw curve balls until they have matured
physically.
Here is what one noted expert
has to say on the subject. Dr. Jack Hutslar of the North American Youth
Sports Institute says, "NO! No curve balls. No sliders." Both pitches
are very stressful on the shoulder and elbow bones and attaching
ligaments. Instead, learn to throw a change up. The most important thing
for young pitchers to learn is this: Pitch using good mechanical form.
Study this in books or videos. At the same time, follow the credo of Ray
Miller, former major league pitching coach. He says "Throw strikes. Change
speeds. Work fast. This works."
More information is available in an
article entitled "Curve Balls: Do They Have A Place in Youth
Baseball" by Michael A Clark of the Youth Sports Institute at
Michigan State University. You can find his article at http://ed-web3.educ.msu.edu/ysi/Spotlight1993/curve.html.
In the article Clark says that the decision on when a youngster should
begin throwing curve balls should be based more on the athlete's physical
maturity than on chronological age.
In the same vein, the total number of
pitches a youngster pitches in the span of a few days is becoming a
growing concern among medical experts. Most youth baseball programs have
limitations on how much and how often pitchers can pitch. Despite the
limitations, overuse injuries by young pitchers are on the rise. Major
league pitchers today usually throw less than 100-120 pitches per game and
pitch with perhaps four days rest. Young kids should not be approaching
100 pitches per game. Youth league coaches should keep track of the number
of pitches a young pitcher throws in a game and how much rest pitcher gets
between starts. The coach should also keep track of the amount the player
throws on the sidelines warming up, during practice and during infield
practice since most youth league pitchers also play shortstop.
